Event-Driven Architecture

Events decouple producers from consumers, enable asynchronous workflows, and give you a replayable history. They also introduce eventual consistency, debugging complexity, and schema-evolution overhead.

Resilience: Circuit Breakers, Retries & Timeouts

Timeouts always. Retries with jitter and a budget. Circuit breakers to fail fast when a dependency is down. Skip any of them and you've built a cascade-failure machine.

API Gateway: When and What For

An API gateway centralizes cross-cutting concerns (auth, rate limit, routing, transformation). It's a force multiplier when used narrowly and a god-object when used as an integration platform.

Backpressure & Load Shedding

When demand exceeds capacity, queue or shed. Queue without limits = OOM. Shed without priority = bad UX. Senior systems decide in advance.

CQRS — When It Pays Off

Separate write model (commands) from read model (queries). Pays off when read/write shapes diverge dramatically or read scale dwarfs write. Otherwise it's just more code.
